[Energy metabolism in the liver and kidneys of rats during the 1st few days after acute hemorrhage].

A relative stability of the adenylate nucleotide system redox of liver and kidney cells was recorded in rats during the first day after acute hemorrhage (2.5% of body weight) in spite of a severe course of the posthemorrhagic period. Energy metabolism was examined in the state of the decompensation of circulation at a blood pressure of 35-45 mm Hg that progressively fell down after a short-term stabilization at the level of 40-60 mm Hg. Comparison of the results obtained with the reported data warrant conclusion that the magnitude of the critical arterial blood pressure at which the test parameters change lies between 40 and 50mm Hg and can vary in relation to a number of the conditions.
